…rhythms. Increased automaticity (in His Purkinje fibers), abnormal automaticity (in contractile myocardium), re entry (anywhere) or triggered activity (anywhere) may all cause ventricular arrhythmias. Indeed…
…attention. The ventricular rate is typically very high (100–250 beats per minute) and cardiac output is affected (i.e reduced) in virtually all cases…
